Entavir 0.5 mg Tablets

Product Details

Entavir 0.5 mg tablet is an antiviral drug and belongs to class of drugs called synthetic nucleoside analogues. It works by blocking the DNA synthesis in hepatitis B virus, a process essential for the virus to grow and multiply. Entavir 0.5 mg tablet thus stops the virus from spreading in the body. It does not prevent spread of HBV infections to other people.Entecavir, a guanosine nucleoside analogue, is a potent and selective inhibitor of hepatitis B virus replication with around 94% patients continuing to remain HBV DNA undetectable and 80% patients with normalization of liver enzymes at the end of 5 years of continuous entecavir therapy. Entecavir resistance is rare in nucleoside-naïve patients, around 1.2% after 5-6 years of treatment. It is recommended as a first line treatment in lamivudine-naïve chronic hepatitis B patients.

Expert advice For Entavir: Do not discontinue taking entecavir without your doctor's advice. Entecavir should be taken on an empty stomach. Please follow the instructions of your doctor. Do consult your doctor before taking entecavir, if you are pregnant or planning to become pregnant. Do consult your doctor before taking entecavir, if you are breast-feeding. Do not drive or operate machines if you feed dizzy, tired or sleepy after taking entecavir. Worsening of hepatitis B may occur while taking entecavir and upon discontinuation. Liver function tests must be conducted while on treatment and upon discontinuation. Consult your doctor before taking entecavir, if you have AIDS or HIV (human immunodeficiency virus) infection. Tests for HIV should be performed before taking entecavir in suspected individuals. Immediately report symptoms such as nausea, vomiting and stomach pain to your doctor. These might indicate development of a life-threatening side effect of entecavir called lactic acidosis (excess lactic acid in blood). Lactic acidosis occurs more often in women, particularly if they are very overweight.
